brain datasets that have missing mri sequences
Finding datasets that naturally feature missing sequences (where patients were simply not scanned with the full protocol) is rare because public repositories usually curate data to ensure completeness. However, several high-profile datasets are specifically designed…
EM algorithm
The Expectation-Maximization (EM) algorithm is an iterative approach to estimate the parameters of probabilistic models, such as a Gaussian (normal) distribution, when the data is incomplete or has missing values. It alternates between two steps:…
ImputeFormer: Low Rankness-Induced Transformers forGeneralizable Spatiotemporal Imputation
The paper “ImputeFormer: Low Rankness-Induced Transformers for Generalizable Spatiotemporal Imputation,” from the KDD ’24 conference, addresses the pervasive issue of missing data in spatiotemporal datasets, particularly contrasting traditional low-rank models with modern deep learning methods like…
